Abstract: A driving circuit electrically coupled between a first data line and a second data line and between a first scan line and a second scan line. The driving circuit includes a first switch, a second switch, a third switch, a fourth switch, a first sub-capacitor, a second sub-capacitor, a fifth switch, a sixth switch, a first voltage dividing unit and a second voltage dividing unit. The first voltage dividing unit is coupled between a second end of the fifth switch and a reference voltage end. The second voltage dividing unit is coupled between a second end of the sixth switch and the reference voltage end, for redistributing stored electric charges.
